To all whom, tmc/y concern:

4Be it known that I, J. E. ANDREWS, of Coeymans Hollow, in the `-countyof Albany and State of New York, have invented a new and usefulImprovement in Machines for Vashing Paper-Stock; and I dohereby declarethat the following is a full, clear, and exact description l thereof,which will enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming part of thisspecification, in which Figure 1 representsa longitudinal sectional Fig.2 represents asection on the line w :c of Fig. l.

Similar letters of reference indicate like parts. i

The nature of my invention relates to improvements inmachines -forwashing paperstock-such as straw. rags, wood liber, .and other similarmaterialnwhether in the condition of pulp or before it is reduced topulp, wherebyit is designed to accomplish the same in a cheaper and moreexpeditious manner than has hitherto been done.

It consists in a water-tank provided with an agitatingavheel, and ahopper adjacent to the same, into which the stock to be washed isplaced,.and so exposed to the action of the iloats onthe wheel that :itwill be drawn down into the water thereby, when it is, after be ingsufficiently agitated in the water, deliv. ered tovainelevatingapparatus, whereby it is raised outof the water and carried to anydesired height and delivered from the same. The said tri-'nk is also.provided with a means of supplying fresh water and discharging the foulwater without carrying off any of the stock, and also with a screen 'forseparating the kernels of grain that may be in the straw, or smallpiecesof gravel or other similar mat ter, as will be -more fully described onreference to the accompanying drawings,

A represents awater-tank, provided with a hopper, B, through which therags are fed into the said tank.

C represents a wheel, provided with iioats C and with wire-screencoverings. j 4

a represents an opening through the sideof the tank' for the foul waterto pass off. A

C, adjacent to the opening `a, which, together side of the tank, form aclose joint, whereby the passage of the water around the end of thewheel to the outlet-passage is prevented,

'hence no water can escape, except it pass D and D represent revolvingcylinders, around which endless chains are passed, to`

which are attached rakes b b and b', for delivering the pulp from thetank.

E represents an inclined chute or spout, in the upper end of which the'roller D is arranged, and which may be carried to any desired height todischarge the stock in the upper stories of the building.

F represents guides or ways arranged on each side of the chute E, andelevated above the bottom of it about the distance of the length. .ofthe teeth ofthe rakes, on which the ends of the rakes ride as they aredrawn upward by the endless chains. To cause the wet stock to be readilydischarged from the rakes, the said ways or guides E are so arrangedthat .as the rakesrise up toward the upper ends of ythe ways they areforced inwardv fromthe straight line,whi ch they would otherwise pursue,toward a line between the axis of the two rollers D and D to such anextent that as they .pass beyond the ends of the said waysthe ad- Grepresents a screen placed at the foot of the incline, which is designedto separate any Vkernels. of grain that may remain in the straw,

or small gravel or other such foul matter.

Power may be applied to the shaft of the l wheel C in any suitablemanner, and be communicated from that to the cylinder D by a belt or bygearing,as may be most desirable.' Having thus described my invention, Iclaim as new and desire to secure byLetters Patent- 1.
